Composite railroad insulators

Composite railroad insulators are made from silicone rubber materials, usually used on railway, also called composite railway insulator.

Composite railroad insulators

In the past decade, polymer insulator usually made in composite suspension insulator used on transmission and distribution lines for 10kv to 1000kv. With the economic developing, railways are built more, more composite railroad insulators are used in railway.

Composite railroad insulators can be divided into
◆ Suspension insulator
◆ Line post insulator for electrical railways

The features of composite railroad insulator
◆ Excellent mechanical strength
◆ Excellent electrical properties
◆ High anti-pollution resistance

Except silicone rubber materials, composite railroad insulators are made of EPDM and epoxy materials. Polymer material can improve composite railroad insulator performance.
